| Jan 15, 2020 at 8:36 | comment | added | eagle275 | @NickMatteo we are on a good way to 8 billion .. but I would appreciate finally going completely IPv6 as it makes things so much easier .. no more punching holes in NAT routers to offer services like personal cloud - and at the same time enough addresses for ANY thinkable device and still having a very large pool of free addresses for more devices in case the population grows further. But this doesn't change the fact that the mentioned sparsity of addresses still originates back to the class-based address distribution which claimed the majority of available addresses for few organizations | |

| Jan 13, 2020 at 16:56 | comment | added | corsiKa | To be clear, how much money would it cost someone to implement this attack? Is it something the average Joe needs to worry it might possibly happen? | |
| Jan 13, 2020 at 15:24 | comment | added | eagle275 | IPv4 addresses are sparse .. hm ,.. in theory 4.295 billion different addresses (minus a few reserved for the unicast / multicast) ... the problem was the initial class based address-reservation and the resulting strong address room fragmentation | |
| Jan 13, 2020 at 14:20 | comment | added | Voo | While this technically answers the question, I imagine the technical details are way too complicated for the OP and even with the disclaimer they might get the wrong idea from this. Sure this is possible and has happened in the past, but only a few larger organisations and states have the capabilities of doing so and it's hard to imagine you'd ever do this to target a single user. There's absolutely no reason for a normal user to worry about this | |
| Jan 13, 2020 at 12:09 | comment | added | Falco | There was a case of erroneous BGP-Advertising several months ago, which broke access to a lot of pages for many users. Which just revealed how incomplete the protections still are in this outdated networking protocol: blog.cloudflare.com/… | |

They would probably have to be in the same area, so they'd be served by the same DHCP server, on the same subnet. Also, unless it's a modified DHCP server, you can also just set a static IP and you don't need to involve DHCP. | |
| Jan 13, 2020 at 7:52 | comment | added | Gnudiff | I think I've seen one of our local telcos, which spans the whole (small) country, give out large subnet real ips to home users via dhcp. Since DHCP frequently tries to give the same address to the same MAC, wouldn't one possiblity be for attacker to clone victim's Mac and (with possibly disabling victim's computer) get the same IP -- they could be physically in another town/district. | |
